Cloning
The biological definition of a clone is an organism that has the same genetic information as another organism or organisms, where else cloning is any process in which production of a clone is successful. These are facts that many people don’t want them to become a reality within our humanity. On the other hand, other people support and want produce human clones. Who’s right? Should we not let science advance freely? Should we take the power of God and mess around with it? Cloning is a big issue these days; the opinion of our community comes into conflict when debating this serious issue.
Amazingly, thefirst attempts at artificial cloning were as early as the beginning of this century. Adolph Eduard Driesch allowed the eggs of a sea urchin develop into the two-blastomere stage. Then he separated it by shaking it in a flask and allowing them to grow. The cells developed into dwarf sea urchins. Driesch could not explain his experiments and gave up embryology for philosophy (McKinnel, 1979).
Thefirst implantation of a nucleus into an egg cell occurred in 1952 by Robert Briggs and Thomas J. King in Philadelphia. They had transferred the nuclei of Leopard Frogs’ eggs (McKinnel, 1979). The egg cells did not develop. Successful cloning of embryo cells was accomplished later in the 1970’s by Dr. John Gurdon.
During the late seventies and early eighties, there were few scientists still studying cloning. Many had predicted that it was impossible to clone embryonic mammal cells. Few continued with research. Many gave up and went into other fields. However, some persisted and were rewarded for their efforts.
In 1984, Dr. Steene Willadsen announced that he had successfully transferred nuclei from embryos of sheep to produce clones (Kolata, 1997). More exciting was when Dr. Neal First produced cows by nuclear transfer from more developed embryos in 1994 (Kolata, 3 June 1997). Dr. First produced four calves. Two years later, …
